Liner Tank Optional Accessories |
On request, Liner-tank.com provides a wide range of optional accessories to satisfy individual customer requirements. These include:
Liner Tank Ladders: Internal and external safety ladders can be supplied for the "Homestead" Range.
Roof Access Manholes: A 450mm diameter manhole and cover are supplied with each standard flat top roof. 600mm, 750mm and 900mm square manholes are available as an option on your liner tank. They consists of a galvanised welded steel angle frame for bolting to the roof sheeting and a sheetmetal cover which is fitted with double stainless steel hinges, hasp and staple, and a padlock.
| Water Tank Level Indicators: There are three types of indicator available: |  |
| • "Levetator" model - the basic type which is fixed to the roof or top edge of the tank. It has no scale or backing board for the indicator. |
|
| • "JHC" model - fixed to the tank with brackets at the top and bottom of the combined indicator guide and scale which is painted white. |
|
| • "Deluxe" model (shown)- indicators consist of a weight with pointer, stainless steel cable and a float. The pointer moves over a scale graduated with horizontal black lines at 100mm intervals and marked with 200mm high numbers at 1m intervals. The scale board is made of folded galvanised sheet - 300mm wide and painted white. Galvanised mild steel brackets and bolts are used to fix the indicator to the tank rings. |
Roof Vents: Roof vents provide ventilation for the air space above the water so as to reduce temperature and humidity and also to provide adequate induct and educt of air during rapid filling or emptying of the tank. Vents are available in a range of sizes and types - including both fixed and rotating.
Standard Liner Tank Pipe Fittings |
|
 |
Anti-Vortex Outlets: These are outlet fittings with baffle plates fitted inside the tank to reduce vortex formation when water is being pumped out. They enable the bottom water level to be lower, thus increasing the effective capacity of the tank. |
 |
Overflow: An overflow is fitted to prevent a tank from being overfilled and allowing water to overflow down the outside of the tank. The overflow size must be sufficient to carry the full inflow rate. Pipework from the overflow must be extended to a drainage point some distance away from the tank base. |
 |
Pipework: Sizes and attachment points will be different for each project. Where specific pipe levels or large diameter flanges are required, check to ensure they clear the tank frame members. Connections should be made using a flange and gasket on both sides of the tank sheet. |
 |
Side Access Manholes are available as a special order |
Scour-Washout Sump: This is fitted in the bottom of the tank so that it can be fully drained. The outlet pipe needs to discharge to a drainage point some distance away from the tank base and be fitted with a lockable gate valve.
Mound Rings: Limited to use with 1.8m and 2.4m high tanks, mound rings are formed from curved galvanised corrugated iron sheets bolted together to form a continuous ring which is then filled with compacted sand. The tank is assembled on this mound and the additional height allows the full tank to be drained when supplying cattle troughing or similar applications.
